If you don't provide details on what is broken in your situation, the odds that 4.1.1 (or any release for that matter) will fix those problems is low.

If others have reported the same symptoms, add a "+1" to that thread if you feel so inclined. Otherwise, please take a moment and document what bugs you have encountered. There's really no other way for us to know of the problems and for you to get the fixes you need.

I think not specifying the specific bug is ok

If Sencha wants detail visibility into people's complaints and reproducible conditions they should publish a bug database so that customers can track issues and hopefully save time trying to send Sencha a bunch of paired-down code. I always hesitate to create something that Sencha can use for bug reproduction because it typically takes a chunk of time out of my week and perhaps another customer has already submitted such a case.
